A singly linked list was previously used to
do fib_info object lookup for various actions
in the routing code.  This does not scale very
well with many devices and even a moderate number
of routes.  This was noted by Benjamin Lahaise.

To fix all of this we use 3 hash tables, two of
which grow dynamically as the number fib_info
objects increases while the final one is fixes in
size.

The statically sized table hashes on device index.
This is used for fib_sync_down, fib_sync_up, and
ip_fib_check_default.

The first dynamically sized table is keyed on
protocol, prefsrc, and priority.  This is used
by fib_create_info() to look for existing fib_info
objects matching the new one being constructed.

The last dynamically sized table is keyed on
the preferred source of the route if it has one
specified.  This is used by fib_sync_down when
a local address disappears.

There are still some scalability problems for
Bens test case in fib_hash.c and I will try to
attack those next.

This makes OProgile use get_task_mm() as discussed.  It also fixes up
Anton's previous patch.  Zwane's soaked this patch all night w/o
problems.

I'm a retard.

Nicolas Boichat reports that his monitor needs the slower
i2c bus timings. These values also match atyfb and the
original ones.

It would clear the segment registers in the parent, which
wasn't really intentional. Noticed by Andries Brouwer.

The final ia64 related cleanup to elf_read_implies_exec() seems to have
broken it.  The effect is that the READ_IMPLIES_EXEC flag is never set
for !pt_gnu_stack binaries!

That's a bit more secure than we need to be, and might break some legacy
app that doesn't expect it.

Correct one Kconfig dependency, which should refer to CONFIG_USERMODE
rather than to CONFIG_UM.

We should also figure out how to make the config process work better for
UML.  We would like to make UML able to "source drivers/Kconfig" and have
the right drivers selectable (i.e.  LVM, ramdisk, and so on) and the ones
for actual hardware excluded.  I've been reading such a request even from
Jeff Dike at the last Kernel Summit, (in the lwn.net coverage) but without
any followup.

This fixes a use-after-free bug in the context switching.  A process going
out of context after exiting wakes up the next process and then kills
itself.  The problem is that when it gets around to killing itself is up to
the host and can happen a long time later, including after the incoming
process has freed its stack, and that memory is possibly being used for
something else.

The fix is to have the incoming process kill the exiting process just to
make sure it can't be running at the point that its stack is freed.
